Lowering Spring Installation DIY



I have had the Eibach Pro-Kit on my FR-S for about a week now, with over 200 miles of spirited driving on the street and in the mountains. I am extremely happy with this product as it simply improves the driver's experience with a slightly stronger connection to the road without being overly harsh.

The drop is advertised as a 1.0" front and rear, although my 2013 FR-S was only lowered 7/8" evenly at all four corners. That is close to an inch, but with the car riding so high to start off with I wish that the error would have been in the other direction. The new look simply removes the unsightly wheel gap that plagues the Scion. The front spring rate is increased by 56% (3.6kg/mm vs 2.7kg/mm stock) and the rear by 29% (4.9kg/mm vs 3.8kg/mm stock) and although this sounds a little extreme, some coilover kits have four times the stiffness of the stock springs.

These springs aren't harsh. Road feel is improved, but I don't cringe when I see a ripple, pothole or driveway. The car has a tendency to bounce just a bit more under aggressive driving on extremely rough surfaces, though, and I would definitely recommend upgrading the dampers (shocks) as a complimentary modification if you plan to take driving seriously. Around town you could easily live with the stock shocks (until they die, possibly)

I would recommend these springs for the BRZ/FR-S owner who simply wants to remove the 4WD look of the car without resorting to any extreme measures. The Eibach brand is an industry staple and customer satisfaction is high. This is a safe bet at a good price.

looks nice! I don't ever upgrade springs without upgrading shocks though.

Well, I have coilovers on the way but I simply couldn't look at the car any longer with the nosebleed altitude.

One thing I don't understand.

How do they measure the spring rates on a progressive coil design?
Did they measure the rate of the first, middle or last section of compression??

Good review. but at the looks of that, I'm going to need at least a 2" drop. I will have nothing less than HELLA FLUSH.

These: http://www.ebay.com/itm/Tein-Tech-Sp...449c6a&vxp=mtr

Look like they could give a bit more of a drop. I'm curious as to what Megan Racing will provide since they always seem to give a lower drop than others.

damn that looks good but not enough drop for me either, i was hoping i could avoid coilovers but maybe not....

The Eibach Sportline springs are a 1.4" drop all around, those are another good alternative to coilovers if you want to save $$$.

thanks for the review! did you by chance take a before and after picture of the wheel gap from the fender to the wheel at close range? id love to see those as well if you did.

Nice post. The car looks great!

Not up close, I didn't. Shoot.

Seems like 19 inch wheels and the lowest drop springs might achieve a decent flush status. But 18 inch wheels and smaller will probably need coilovers.

its all good. all you really have to do is get another board member with the same color car to take the stock height photo, then you yourself take the photo of your car as it is now. Overall, looks really good, what shocks are you eventually switching to once the stockies go?

I have coilovers on the way, these springs are just temporary until the coilovers show.

any updates? did your car ever settle at the full 1inch drop?

Needs more low.

If you can fit your hand in it, it's not low enough.

You rears especially. :thumbsup:

:happy0180:

money much? what coilover set did you get?

if you can fit your hand in, that means you have suspension travel and your car won't skid at the slightest bump in a corner.

Anyone know if these are actually in stock/ready to ship? I've checked everywhere and most websites aren't getting these springs 'til the end of July, find it hard to believe that this guy is sitting on a nice stock of them ready to ship/sell.

Nope. 7/8" and I've put hundreds of miles on the car. I don't think it's going down any more.

KWs showed up last week, but I am waiting for D2s to arrive. I want to try the $1000 set before deciding to install or sell the $2000 set.

A similar review of the D2's would be awesome and much appreciated. Not that this one wasn't.

I will definitely do that.

Nice to see your eibach prokit. Nice drop compare to stock. The drive diffinitely improved over stock in handling. I currently have the sportlines. Car has good handling thru curves at high speed

Darren, great review! Thanks!

Our Eibach engineers design the springs around the factory shocks. We rate test the factory springs and shock dyno the factory shocks. A sport tuned shock should would perform better over a factory shock, of course. But the factory shocks will perform well enough for street use.

We've been shipping these since the end of last month. Some distributors may have gotten them sooner than others based on their location. We definitely have plenty of these in stock and ready to ship.

Can I get a link to an order page? Or a pm with details on how to get these, definitely want them asap.

Hey AJUSA, please keep the commercial replies in the commercial forum and don't hijack my review to sell product. Thanks.

We are the manufacturer and, unfortunately, we do not sell direct to retail customers. I would recommend contacting Evasive at the link below or one of the other dealers advertising in the link Darren provided above.

can you post some pics of how your car sits on the sportlines? these are the springs i'm looking to get and i want to see how low they drop the car.

Here you go - quoted from another thread

Oops, I should have added those to the first page... fixed that. Thanks.

Any chance of some profile pics @DarrenDriven to see how much they poke now.
Just to confirm that at the moment you have the Rota Torque 17x9 +30 and lowering springs - thats it wheels and suspension wise (until your coil overs arrive).
Any rub issues?

Yeah, I will take some soon.

No rubbing at all with the 1" drop and 17x9.0 +30, but I am still going to get the front pair of wheels machined slightly to raise the offset about 10mm.

It really just strikes me as the way the car should have come in the first place. Not scraping-the-speedbumps low, just sexy low. Car looks great!

that looks awesome!!! im 100% sold now lol

how much negative camber did u get at the front after the springs? u reckon 18x8.5 +38 wheels will be tucked in??

Hey thanks, we sure like it! Yours looks great as well Darren, want to see it in person some day. I'm not really sure about the camber, I had Les Schwab install them for me and my wife picked it up so I didn't get a chance to talk to them after. I wanted to go 8.5, but they advised against it. But honestly, I think you'd be just fine after looking at mine with 8.0 wheels.

Any issues with shock travel or hitting the bump stops?

Really nice! I'm considering this set up on mine. Nice, simple, classy, and not too expensive.

No bottoming out, and it comes with new bump stops anyway so I think that helps. Feels just a little stiffer than stock, like how it LOOKS like it should feel, if that makes sense.

did u have any camber problems with only droping 1 inch ? and if so what did u do to currect this ? thanks
